To dig you need 151 happiness. You gain happiness by KOing Pokemon and walking with your Pokemon for a while.
You can check your Pokemon's happiness by typing "/happy 1-6" in chat. For your Cyndaquil it would be "/happy 1" as it is in the first slot.
He already has 151+ happiness if you look at the picture i think this is some bug
Get it to full happiness just in case.

Both servers are online but server is also having trouble it might cause you not to be able to login. Like Jolly said try to reinstall and just spam that login button till it says Logging in.
